Water parameters

Temp 76-80 F Temperature

Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.

pH 7.8 - 8.4 potential of Hydrogen

Measuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.

NO3 1-20 ppm Nitrate

While less toxic than ammonia, high nitrate levels (above 40–80 ppm) are important to monitor because they can cause fish stress, stunted growth, and harmful algae blooms.

NO2 <0.0001 ppm Nitrite

It is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia

PO4 0.01 - 0.1 ppm Phosphate

It is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.

NH3 <0.1 ppm Ammonia

It is the primary killer of aquarium fish, causing gill damage, stress, and death

Ca 380 - 450 ppm Calcium

Supporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae

KH 8 - 12 dKH Alkalinity

It acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.

Mg 1200 - 1400 ppm Magnesium

It enables coral growth by supporting skeletal formation, assists in metabolic processes, and ensures that calcium is available for corals, clams, and coralline algae.

SG 1.023 - 1.026 SG Salinity

Essential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals

ORP 250 - 400 mV Oxidation-Reduction Potential

A higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.

About Swissguard Basslet

General information

The Swissguard Basslet (Liopropoma rubre) is a popular aquarium fish known for its bright red coloration and attractive appearance. These fish are relatively small, growing to an average size of around 3-4 inches (7.5-10 cm) in length. They are native to the Caribbean Sea, and can be found in a variety of reef habitats. In the wild, Swissguard Basslets are often found in small groups or pairs, and they are a popular choice for reef aquariums due to their peaceful nature and ease of care.

Diet & nutrition

Swissguard Basslets are carnivorous and require a diet that is high in protein. They will readily accept a variety of meaty foods such as frozen or live brine shrimp, mysis shrimp, and chopped squid or shrimp. It is important to provide a varied diet to ensure that they receive all the necessary nutrients.

Determining sex

There is no known external difference between males and females of the Swissguard Basslet species.

Breeding & spawning

Swissguard Basslets are known to be difficult to breed in captivity, and there is limited information available about their breeding habits. It is believed that they are egg-layers, with males and females releasing their gametes into the water column to fertilize externally.

Diseases

Swissguard Basslets are generally hardy and not susceptible to many diseases if kept in a clean and well-maintained aquarium. However, like all fish, they are susceptible to parasitic infections and bacterial diseases. Keeping the aquarium clean and well-maintained, and quarantining new fish before adding them to the main tank, can help prevent the spread of disease.

Origination

Swissguard Basslets are native to the Caribbean Sea.

Cautions

Swissguard Basslets are generally peaceful and do not pose any threats to humans. However, they may be aggressive towards other fish of the same species or similar appearance, so it is best to keep them in a tank with peaceful tankmates.

Acclimation process

When introducing Swissguard Basslets to a new aquarium, it is important to acclimate them slowly to avoid shock. This can be done by floating the bag containing the fish in the aquarium for about 20 minutes, then gradually adding small amounts of water from the aquarium to the bag over a period of several hours.
